| titleOfInvention | Crack retardant mixture for concrete and concrete by using it |
| abstract | The present invention relates to a concrete composition for reducing shrinkage used in concrete structures, to prevent dry shrinkage to prevent cracking and to provide a shrinkage reducing material having a high expression rate of long-term compressive strength and a concrete composition using the reducing material.n n n The present invention for achieving the above objectn n n Mixing the hydrated lime (Ca (OH) 2 ) suspension with a water absorbent in a gas containing a large amount of sulfurous acid gas at 200 ° C to 300 ° C, and mixing the remaining 5 to 70% by weight of gypsum slag powder with the remaining 30 to 95% blast furnace slag powder. Shrinkage reducing materialn n n (a) cement: 70-85 wt%n n n (b) The shrinkage reducing material: The raw material which mix | blended 15-30 weight% with respect to the concrete composition comprised from the sand of a granulation rate (F.M) 2.8 or more or an aggregate within 50 mm is made into the technical summary. |
